DETAILED DESCRIPTION

As described in this document, embodiments are directed to a gamecontroller for a mobile device with a hold-open feature.

Keeping the handles pulled apart while inserting the mobile device intoa game controller can be difficult. For example, a user holding a mobiledevice in the user's right hand may need to use the user's left hand topull the two handles apart when placing the mobile device between thetwo handles of the game controller. This difficulty with insertion maybe exacerbated when the game controller connects to the mobile devicevia a connector, such as USB-C connector, because the user must alsoensure that the mobile device is aligned with the connector wheninserting it. The removal of the mobile device may be equally vexing asthe user must once again attempt to pull the two handles apart with onehand.

But in embodiments of the disclosed game controller, once the handlesare pulled apart sufficiently, the handles lock in place, allowing theuser to easily insert the mobile device. Then, by applying lightpressure on the handles, the user can unlock the handles and snap thedevice shut, securing the mobile device to the game controller.

FIG. 1 is a perspective view showing portions of a game controller 100,according to embodiments. As illustrated in FIG. 1, a game controller100 may include a first handle 101, a second handle 102, and a bridge119. Each of the first handle 101 and the second handle 102 isconfigured to contact and support a mobile device 199, though not allcontemplated embodiments will include the second handle 102. Anexemplary mobile device 199 is shown in broken lines to illustrate howthe game controller 100 may contact and support a mobile device 199 insome embodiments. The mobile device 199 may be, as examples, asmartphone or a tablet computer.

As illustrated in FIG. 1, the first handle 101 includes a guide portion113 and a main body portion 105. The guide portion 113 extends from themain body portion 105 and along a first end 115 of the span 120 of thebridge 119. (See also FIGS. 5 and 6.) The guide portion 113 of the firsthandle 101 is configured to align the bridge 119 with the main bodyportion 105 of the first handle 101.

As illustrated, the first handle 101 includes a user-accessible, firsthardware interface 103 on the main body portion 105 of the first handle101. The first hardware interface 103 could be a button, an analogstick, a touchscreen, a touchpad, a knob, a slider, a switch, a wheel, adial, a directional pad, or another such feature configured to accepttouch inputs from a user's finger or a stylus. As shown in FIG. 1, thefirst hardware interface 103 may include multiple such hardwareinterfaces.

Likewise, the second handle 102 includes a guide portion 114 and a mainbody portion 106. The guide portion 114 extends from the main bodyportion 106 and along a second end 116 of the span 120 of the bridge119. (See also FIGS. 5 and 6.) The guide portion 114 of the secondhandle 102 is configured to align the bridge 119 with the main bodyportion 106 of the second handle 102.

As illustrated, the second handle 102 further includes auser-accessible, second hardware interface 104 on the main body portion106 of the second handle 102. As above for the first hardware interface103 of the first handle 101, the second hardware interface 104 could bea button, an analog stick, a touchscreen, a touchpad, a knob, a slider,a switch, a wheel, a dial, a directional pad, or another such featureconfigured to accept touch inputs from a user's finger or a stylus. Thesecond hardware interface 104 may include multiple such hardwareinterfaces, as illustrated in FIG. 1.

One or both of the first handle 101 and the second handle 102 mayinclude a connector 125 for physical and electrical connection to themobile device 199. The connector 125 may be, for example, a USB-Cconnector.

FIGS. 2-4 are top views of the game controller 100 of FIG. 1, showing anexample process of how the game controller 100 may contact and supportan example mobile device 199. As illustrated in FIG. 2, the mobiledevice 199 may be placed over the bridge 119, between the first handle101 and the second handle 102 of the game controller 100. As illustratedin FIG. 3, the connector 125 of the game controller 100 may be joinedwith a corresponding connector on the mobile device 199. FIGS. 2 and 3show examples of an extended configuration of the game controller 100.In FIG. 4, the mobile device 199 is secured between the first handle 101and the second handle 102 of the game controller 100. FIG. 4 illustratesan example of a retracted configuration of the game controller 100. Theextended configuration and the retracted configuration of the gamecontroller 100 will be described in more detail below. The reader willnote, though, that there is more than one retracted configuration. Forexample, FIG. 4 illustrates an example of a retracted configuration whenthe game controller 100 is securing a mobile device 199. As anotherexample, FIG. 5 (described below) illustrates an example of a retractedconfiguration when the game controller 100 is not securing a mobiledevice 199.

FIG. 5 is a front, partial sectional view of the game controller 100 ofFIG. 1 in an example of a retracted configuration of the game controller100. FIG. 6 is a front, partial sectional view of the game controller100 of FIG. 1 in an example of an extended configuration of the gamecontroller 100. As illustrated in FIGS. 5-6, a game controller 100 mayinclude a first handle 101, a second handle 102, and a bridge 119, eachas described above for FIGS. 1-4. In each of FIGS. 5-6, externalportions of the first handle 101, the second handle 102, and the bridge119 are not shown to make certain internal features visible.

As illustrated, the bridge 119 is in sliding engagement with the firsthandle 101. As illustrated, the bridge 119 is not telescoping, meaningthat segments of the bridge 119 do not slide within another segment ofthe bridge 119 to allow for lengthening or shortening of the bridge 119.The bridge 119 has a span 120 extending away from the main body portion105 of the first handle 101, and the span 120 has a transverse midline121.

The bridge 119 and the first handle 101 are configured to allow the mainbody portion 105 of the first handle 101 to translate in a retractiondirection 122 toward the midline 121 of the bridge 119 and into aretracted configuration, such as one of the example retractedconfigurations illustrated in FIG. 4 or 5. The bridge 119 and the firsthandle 101 are configured to allow the main body portion 105 of thefirst handle 101 to also translate in an extension direction 123 awayfrom the midline 121 of the bridge 119 into an extended configuration,such as one of the example extended configurations illustrated in FIG. 2or 6.

As used in this disclosure, the transverse midline 121 of the bridge 119is a reference datum used to define the extension direction 123 and theretraction direction 122. That is, the retraction direction 122 istoward the transverse midline 121, while the retraction direction 122 isaway from the transverse midline 121. Accordingly, the transversemidline 121 of the bridge 119 may or may not coincide with a physicalstructure on the game controller 100.

Likewise, the bridge 119, as illustrated, is in sliding engagement withthe second handle 102, and the span 120 of the bridge 119 extends awayfrom the main body portion 106 of the second handle 102. The bridge 119and the second handle 102 are configured to allow the main body portion106 of the second handle 102 to translate in the retraction direction122 toward the midline 121 of the bridge 119 and into the retractedconfiguration. The bridge 119 and the second handle 102 are configuredto allow the main body portion 106 of the second handle 102 to alsotranslate in the extension direction 123 away from the midline 121 ofthe bridge 119 into the extended configuration.

As illustrated in FIGS. 5-6, the game controller 100 may also include afirst spring mechanism 107, a second spring mechanism 108, a first latchmechanism 109, a second latch mechanism 110, a first linear rack 111, asecond linear rack 112, and a pinion 124. These are described below.

The first spring mechanism 107 is configured to bias the first handle101 toward the retracted configuration. In addition, the first springmechanism 107 exerts a first retraction force on the first latchmechanism 109 in the retraction direction 122. As illustrated, the firstspring mechanism 107 may be attached to the first handle 101 through ashaft 117 and is also attached to the bridge 119. The first springmechanism 107 may be or include a first constant-load spring connectingthe first handle 101 to the bridge 119. The first constant-load springis configured to exert a substantially constant force on the firsthandle 101 in the retraction direction 122. As used in this disclosure,“substantially constant” means largely or essentially invariable, yetwithout requiring perfect constancy, as the game controller 100transitions from the retracted configuration to the extendedconfiguration and from the extended configuration to the retractedconfiguration.

The second spring mechanism 108 is configured to bias the second handle102 toward the retracted configuration. In addition, the second springmechanism 108 exerts a second retraction force on the second latchmechanism 110 in the retraction direction 122. As illustrated, thesecond spring mechanism 108 is attached to the second handle 102 througha shaft 118 and is also attached to the bridge 119. The second springmechanism 108 may be or include a second constant-load spring connectingthe second handle 102 to the bridge 119. The second constant-load springis configured to exert a substantially constant force on the secondhandle 102 in the retraction direction 122.

The first latch mechanism 109 is configured to temporarily lock thebridge 119 in the extended configuration. The first latch mechanism 109is further configured to require a first disengagement force in theretraction direction 122 to unlock the bridge 119 from the extendedconfiguration. The first disengagement force is greater than the firstretraction force exerted by the first spring mechanism 107 in theretraction direction 122. The additional force (that is, that portion ofthe first disengagement force that exceeds the first retraction force)may be provided by, for example, pressure from the user's hands exertedin the retraction direction 122.

Likewise, the second latch mechanism 110 is configured to temporarilylock the bridge 119 in the extended configuration. The second latchmechanism 110 is further configured to require a second disengagementforce in the retraction direction 122 to unlock the bridge 119 from theextended configuration. The second disengagement force is greater thanthe second retraction force exerted by the second spring mechanism 108in the retraction direction 122. The additional force (that is, thatportion of the second disengagement force that exceeds the secondretraction force) may be provided by, for example, pressure from theuser's hands exerted in the retraction direction 122.

As illustrated, the first linear rack 111 is coupled to the first handle101 and is in sliding engagement with the bridge 119. The first linearrack 111 extends substantially along the span 120 of the bridge 119. Asused in this disclosure, “substantially along” means largely oressentially in the direction of, without requiring perfect conformity.The first linear rack 111 may further include a step 126 or indentation,which may engage with the first latch mechanism 109 as described morefully below. As used in this disclosure, “to engage” means “to interlockwith; to fit together.”

The second linear rack 112 is coupled to the second handle 102 and is insliding engagement with the bridge 119. The second linear rack 112extends substantially along the span 120 of the bridge 119. The secondlinear rack 112 may further include a step 126, which may engage withthe second latch mechanism 110 as described more fully below.

As illustrated, the pinion 124 is affixed to the bridge 119. The pinion124 is in contact with each of the first linear rack 111 and the secondlinear rack 112. The pinion 124 is configured to rotate relative to thebridge 119 as the first linear rack 111 is translated relative to thepinion 124. The pinion 124 is also configured to rotate as the secondlinear rack 112 is translated relative to the pinion 124.

FIG. 7 is a close-up of a portion of the game controller 100 of FIGS. 5and 6, illustrating an example latch mechanism in an unlatchedconfiguration. FIG. 8 is a close-up of a portion of the game controller100 of FIGS. 5 and 6, illustrating the example latch mechanism of FIG. 7in a latched configuration. While illustrated and described for thefirst-handle side of the game controller 100, the discussion for FIGS. 7and 8 applies equally to the second-handle side of the game controller100. Hence, the example latch mechanism of FIGS. 7 and 8 may be thefirst latch mechanism 109 described above for FIGS. 5 and 6, the secondlatch mechanism 110 described above for FIGS. 5 and 6, or both the firstlatch mechanism 109 and the second latch mechanism 110.

As illustrated in FIGS. 7 and 8, the example latch mechanism may includea catch 127 coupled to the bridge 119. The catch 127 is configured tocontact and engage the step 126 on the first linear rack 111 in theextended configuration and disengage from the step 126 on the firstlinear rack 111 in the retracted configuration. To facilitate theengagement and disengagement of the catch 127 from the step 126, thestep 126 may be angled or rounded, or a portion of the catch 127 facingthe step 126 may be angled or rounded, or both.

As illustrated, the catch 127 is coupled to the bridge 119 through apivot 128. The first latch mechanism 109 may also include a cantileveredspring 129 configured to apply a torque to the catch 127 about the pivot128 to bias the catch 127 against the first linear rack 111. Thecantilevered spring 129 may be coupled to the bridge 119 by one or moreattachment points 130.

With particular reference to FIGS. 2-8, in use the game controller 100may initially be in a retracted configuration, such as the retractedconfiguration illustrated in FIG. 5. In the retracted configuration, thecatch 127 is disengaged from the step 126 on the first linear rack 111.In versions having a catch 127 on a second linear rack 112 (also orinstead of the catch 127 on the first linear rack 111), in the retractedconfiguration, the catch 127 is disengaged from the step 126 on thesecond linear rack 112.

Then, the user may apply a force (using, for example, the user's hands)to the first handle 101 or the second handle 102, or both, in theextension direction 123 to move the game controller 100 into an extendedconfiguration, such as the extended configurations illustrated in FIGS.1,2, and 6. In other words, the user may pull the first handle 101 andthe second handle 102 apart from each other.

In transitioning to the extended configuration, the first linear rack111 slides relative to the catch 127 for the first end 115 of the span120 until that catch 127 is aligned with the step 126 in the firstlinear rack 111. During the transition, the first spring mechanism 107continues to bias the first handle 101 toward the retractedconfiguration and exerts a first retraction force on the first latchmechanism 109 in the retraction direction 122. The cantilevered spring129 then causes the catch 127 for the first end 115 of the span 120 toengage the step 126 of the first linear rack 111 by forcing the catch127 into the step 126. The first latch mechanism 109 is now temporarilylocking the bridge 119 in the extended configuration by way of the catch127.

In versions having a catch 127 on a second linear rack 112 (also orinstead of the catch 127 on the first linear rack 111), in transitioningto the extended configuration, the second linear rack 112 slidesrelative to the catch 127 for the second end 116 of the span 120 untilthe catch 127 is aligned with the step 126 in the second linear rack112. During the transition, the second spring mechanism 108 continues tobias the second handle 102 toward the retracted configuration and exertsa second retraction force on the second latch mechanism 110 in theretraction direction 122. The cantilevered spring 129 then causes thecatch 127 for the second end 116 of the span 120 to engage the step 126of the second linear rack 112 by forcing the catch 127 into the step126. The second latch mechanism 110 is now temporarily locking thebridge 119 in the extended configuration by way of the catch 127.

With the bridge 119 temporarily locked in the extended configuration,the user may then insert a mobile device 199 into the game controller100 by placing the mobile device 199 over the bridge 119, such asillustrated in FIG. 2. If necessary, the connector 125 of the gamecontroller 100 may then be joined with a corresponding connector on themobile device 199, such as illustrated in FIG. 3.

To unlock the hold-open feature, where the bridge 119 is temporarilylocked in the extended configuration, and return the game controller 100to a retracted configuration, the user typically applies a force to thefirst handle 101 in the retraction direction 122. This user-appliedforce, coupled with the first retraction force exerted by the firstspring mechanism 107, causes the catch 127 for the first end 115 of thespan 120 to disengage from the step 126 in the first linear rack 111.Once disengaged, the first retraction force exerted by the first springmechanism 107 causes the game controller 100 to transition to aretracted configuration.

In versions having a catch 127 on a second linear rack 112 (also orinstead of the catch 127 on the first linear rack 111), the user mayapply a force to the second handle 102 in the retraction direction 122.This user-applied force, coupled with the second retraction forceexerted by the second spring mechanism 108, causes the catch 127 for thesecond end 116 of the span 120 to disengage from the step 126 in thesecond linear rack 112. Once disengaged, the second retraction forceexerted by the second spring mechanism 108 causes the game controller100 to transition to a retracted configuration.

Since moving the game controller 100 from the retracted configuration tothe extended configuration is often done by using both of the user'shands (such as, for example, one hand on each of the first handle 101and the second handle 102), the hold-open feature allows the user—oncethe game controller 100 is temporarily locked in the extendedconfiguration—to remove one or both of the user's hands from the gamecontroller 100 (such as, for example, from either the first handle 101or the second handle 102, or both) to manipulate the mobile device 199into position, such as the position illustrated in FIG. 2. Hence,embodiments of the disclosed technology allow the user to efficientlyand easily insert and remove a mobile device 199 from the gamecontroller 100.

FIG. 9 is a close-up of a portion of an alternative arrangement for thegame controller 100 of FIGS. 5 and 6, illustrating an example latchmechanism in an unlatched configuration. FIG. 10 is a close-up of aportion of an alternative arrangement for the game controller 100 ofFIGS. 5 and 6, illustrating the example latch mechanism of FIG. 9 in alatched configuration. While illustrated and described for thefirst-handle side of the game controller 100, the discussion for FIGS. 9and 10 applies equally to the second-handle side of the game controller100. Hence, the example latch mechanism of FIGS. 9 and 10 may be thefirst latch mechanism 109 described above for FIGS. 5 and 6, the secondlatch mechanism 110 described above for FIGS. 5 and 6, or both the firstlatch mechanism 109 and the second latch mechanism 110.

As illustrated in FIGS. 9 and 10, the example latch mechanism mayinclude a tension spring 132 coupled to the bridge 119. An engagementportion 131 of the tension spring 132 is configured to contact andengage the step 126 on the first linear rack 111 in the extendedconfiguration and disengage from the step 126 on the first linear rack111 in the retracted configuration. To facilitate the engagement anddisengagement of the catch 127 from the step 126, the step 126 may beangled or rounded.

As illustrated, the tension spring 132 is coupled to the bridge 119through one or more attachment points 133. The tension spring 132 isconfigured to bias the engagement portion 131 of the tension spring 132against the first linear rack 111. The engagement portion 131 isconfigured to engage the step 126 in the extended configuration.

Accordingly, in transitioning from the retracted configuration (anexample of which is illustrated in FIG. 9) to the extended configuration(an example of which is illustrated in FIG. 10), the first linear rack111 slides relative to the engagement portion 131 of the tension spring132 until the engagement portion 131 is aligned with the step 126 in thefirst linear rack 111. The tension spring 132 then causes the engagementportion 131 to engage the step 126 of the first linear rack 111 byforcing the engagement portion 131 into the step 126. Likewise, intransitioning from the extended configuration to the retractedconfiguration, the engagement portion 131 of the tension spring 132 isdisengaged from the step 126 in the first linear rack 111. Otherwise,operation of this example latch mechanism is substantially as describedabove for FIGS. 2-8.

FIG. 11 is a close-up of a portion of an alternative arrangement for thegame controller 100 of FIGS. 5 and 6, illustrating an example latchmechanism in an unlatched configuration. FIG. 12 is a close-up of aportion of an alternative arrangement for the game controller 100 ofFIGS. 5 and 6, illustrating the example latch mechanism of FIG. 11 in alatched configuration. While illustrated and described for thefirst-handle side of the game controller 100, the discussion for FIGS.11 and 12 applies equally to the second-handle side of the gamecontroller 100. Hence, the example latch mechanism of FIGS. 11 and 12may be the first latch mechanism 109 described above for FIGS. 5 and 6,the second latch mechanism 110 described above for FIGS. 5 and 6, orboth the first latch mechanism 109 and the second latch mechanism 110.

As illustrated in FIGS. 11 and 12, the example latch mechanism mayinclude a catch 134 coupled to the bridge 119. The catch 134 isconfigured to contact and engage the step 126 on the first linear rack111 in the extended configuration and disengage from the step 126 on thefirst linear rack 111 in the retracted configuration. To facilitate theengagement and disengagement of the catch 134 from the step 126, thestep 126 may be angled or rounded, or a portion of the catch 134 facingthe step 126 may be angled or rounded, or both.

As illustrated, the catch 134 is coupled to the bridge 119 through apivot 135. The first latch mechanism 109 may also include a cantileveredspring 136 configured to apply a torque to the catch 134 about the pivot135 to bias the catch 134 against the first linear rack 111. Asillustrated, the cantilevered spring 136 may be integral to and extendfrom the catch 134. Accordingly, the cantilevered spring 136 may beconfigured to slide through one or more guide points 137 of the bridge119, which constrain an end of the cantilevered spring 136 opposite thecatch 134.

Operation of this example latch mechanism is substantially as describedabove for FIGS. 2-8.

FIG. 13 is a close-up of a portion of an alternative arrangement for thegame controller 100 of FIGS. 5 and 6, illustrating an example latchmechanism in an unlatched configuration. FIG. 14 is a close-up of aportion of an alternative arrangement for the game controller 100 ofFIGS. 5 and 6, illustrating the example latch mechanism of FIG. 13 in alatched configuration. While illustrated and described for thefirst-handle side of the game controller 100, the discussion for FIGS.13 and 14 applies equally to the second-handle side of the gamecontroller 100. Hence, the example latch mechanism of FIGS. 13 and 14may be the first latch mechanism 109 described above for FIGS. 5 and 6,the second latch mechanism 110 described above for FIGS. 5 and 6, orboth the first latch mechanism 109 and the second latch mechanism 110.

As illustrated in FIGS. 13 and 14, the example latch mechanism mayinclude an elastic body 138 coupled to the bridge 119. The elastic body138 is configured to contact and frictionally engage a raised portion139 on the first linear rack 111 in the extended configuration anddisengage from the raised portion 139 in the retracted configuration. Tofacilitate the engagement and disengagement of the elastic body 138 fromthe raised portion 139, the raised portion 139 may be angled or rounded,or the raised portion 139 may be angled or rounded, or both. Asillustrated, the elastic body 138 is configured to elastically distortwhen engaged with the raised portion 139 of the first linear rack 111.

Accordingly, in transitioning from the retracted configuration (anexample of which is illustrated in FIG. 13) to the extendedconfiguration (an example of which is illustrated in FIG. 14), the firstlinear rack 111 slides relative to the elastic body 138 until theelastic body 138 contacts the raised portion 139 of the first linearrack 111. The elastic body 138 then elastically distorts andfrictionally engages the raised portion 139 on the first linear rack111. Likewise, in transitioning from the extended configuration to theretracted configuration, the elastic body 138 is disengaged from theraised portion 139 of the first linear rack 111. Otherwise, operation ofthis example latch mechanism is substantially as described above forFIGS. 2-8.

FIG. 15 is a close-up of a portion of an alternative arrangement for thegame controller 100 of FIGS. 5 and 6, illustrating an example latchmechanism in an unlatched configuration. FIG. 16 is a close-up of aportion of an alternative arrangement for the game controller 100 ofFIGS. 5 and 6, illustrating the example latch mechanism of FIG. 15 in alatched configuration. While illustrated and described for thefirst-handle side of the game controller 100, the discussion for FIGS.15 and 16 applies equally to the second-handle side of the gamecontroller 100. Hence, the example latch mechanism of FIGS. 15 and 16may be the first latch mechanism 109 described above for FIGS. 5 and 6,the second latch mechanism 110 described above for FIGS. 5 and 6, orboth the first latch mechanism 109 and the second latch mechanism 110.

As illustrated in FIGS. 15 and 16, the example latch mechanism mayinclude one or more resilient clips 140 on the first handle 101. Asillustrated, the resilient clip 140 may be within the guide portion 113of the first handle 101. The resilient clip 140 is configured to contactand engage an outer edge of the bridge 119 in the extended configurationand to disengage from the outer edge of the bridge 119 in the retractedconfiguration. To facilitate the engagement and disengagement of theresilient clip 140 from the outer edge of the bridge 119, the resilientclip 140 may be angled or rounded, the outer edge may be angled orrounded, or both. The resilient clip 140 is biased against the outeredge of the bridge 119. As illustrated in FIG. 15, the resilient clips140 may be disengaged from the outer edge of the bridge 119 while stillbeing in contact with the outer edge.

As illustrated in FIG. 16, the resilient clip 140 engages a terminus ofthe bridge 119. In other embodiments, the resilient clip 140 may engagean indentation or step on the outer edge of the bridge 119, theindentation or step not being at the terminus of the bridge 119.

Alternatively, one or more resilient clips 140 may be on the bridge 119and be configured to contact and engage the first handle 101 in theextended configuration and to disengage from the first handle 101 in theretracted configuration.

With specific reference to the embodiment illustrated in FIGS. 15 and16, in transitioning from the retracted configuration (an example ofwhich is illustrated in FIG. 15) to the extended configuration (anexample of which is illustrated in FIG. 16), the bridge 119 slidesrelative to the first handle 101 until the resilient clip 140 engagesthe terminus of the bridge 119. Likewise, in transitioning from theextended configuration to the retracted configuration, the resilientclip 140 is disengaged from the terminus of the bridge 119. Otherwise,operation of this example latch mechanism is analogous to what isdescribed above for FIGS. 2-8.
